Chapter 875: A Powerful Foe

'Hehe, unfortunately for you, I'm already undefeatable in the Sage Plane.' Grey snickered internally and his aura surged. 

Boom! 

The attack of the man and Grey collided and the man was forced back a few steps. When he looked at Grey, his eyes opened wide and his mouth dropped. 

"How?" He blurted out unconsciously. 

Grey just went from the Second stage of the Sage Plane to the Peak in less than a second. This was something that shouldn't be possible. 

'Unless… he was hiding his cultivation. That's it!' The man thought in realization. 

This was the only explanation he could come up with. 

He accessed Grey once again before nodding, "No wonder you were marked. So young but already so powerful. You'll fit nicely into my collection."

"I was about to say the same to you." Grey commented offhandedly.
